铀矿床围岩蚀变是成矿热液和岩石液-固相间的化学反应产物,是成矿热液作用历史的记录。因此,矿床蚀变地球化学研究在矿床成因理论上和找矿实践中都具有重要意义。在讨论铀矿床近矿蚀变之前,首先必须指出:第一,从大量铀矿床的已有资料得出,含铀热液几乎并不直接与未蚀变原岩发生反应,而成矿蚀变是建筑在成矿前蚀变自然底场(自
Surrounding rock alteration of uranium deposit is a chemical reaction product between hydrothermal fluid and rock liquid - solid phase and is a record of the history of the hydrothermal fluid. Therefore, the alteration geochemistry of ore deposits is of great significance in the theory of deposit genesis and prospecting practice. Before discussing uranium deposit near ore alteration, we must first point out: first, from the available data of a large number of uranium deposits, uranium-bearing hydrothermal fluids do not almost directly react with undamaged protoliths, and mineralization alteration Is the construction of alterations before mineralization bottom field (since
